FIR filter impulse response has ______________________ both numerator and denominator polynomail only numerator polynomail only denominator polynomail constant values FIR filters satisfy following characteristics. If input is applied as all zero sequence for same length of an impulse response then their output is always zero They can implement given filter specification at lower computational cost. Their phase response can be linear They are inherently stable provided bounded input is applied
